170 LEZ whom, t may concern;

Be it known that we, WILLIS C. LEE and MILES F.MOORE,citizens oftheUnited States,

residing at South Chicago, a part of the cityV of Chicago, in the countyof Cook and State of Illinois, have invented a new and usefulCombination Crossing and Double Slip- Switch with Movable Center Points,of which the following is a specification in its best form now known tous, reference being had to the `accompanying drawings, in. which similarcharacters indicate the saine parts throughout the several views.

Our invention relates to com bined railroadcrossings and slip-switches;and the object of our invention iS-to produce such mechan- I ism in'whichit is possible when it is properly set for a train to cross atdifferent tilnes .on

either track and also by properly settingthe switchesto be transferredfrom either diago-` nal track to the other of said crossings.

Our invention particularly relates to lnech` anisln for controlling such`a combination crossing and double slip-switch with movablecenter-points by a single lever, preferably mounted in the switch-standadjacent to the track, so that by moving this single lever to successivepositions the switches on the crossl ing willbe successively set for a.crossing on one track, a slip-switch from one track to the other, athrough-crossing on the other track, and the use of the oppositeslip-switch.

Our invention also consists in the colnbi-` nation, with the above, of asystem of signals sage of trains at least one of the two signalsreferred `to `will show danger.

Our invention consists in a combined `switch-crossing having all of theabove ad-V vantages which can` be more easily and cheaply constructedand which is less liable toget ont of order than any heretofore made;`and italso consists in many details of con- Al, 2, 3, and 4.

struction hereinafter more fully described and claimed.

Referring to the drawings, Figure 1 is a plan view of mechanismillustrating our invention, showing one main track set for tion of theparts when the opposite throughtrack from the one shown in Fig. 1 isready for use, and Fig. 4 shows the position of the parts wllen theOpposite slip-switch from the one shownin Fig. 2 is ready for use. Fig.5 is a detailplan, and Fig. 6 is a detail sectional View, of theconnections of the four end switch-points and the signals connected tothe Sallie. Fig. 7 is a side elevation of the switch-stand preferablyused in our invention. Fig. 8 is a sectional detail view ofthe upperportion of the stand, taken diagonally from the base of the stand online S of Fig. 1. Fig. 9 is a detail sectional view of the lower portionof the switch-stand, taken directly through the center of the stand onthe dotted line 9 of Fig. 1. Figs. 10, 11, 12, and 13 are respectivelydetail plan views taken on the lines 10, 11, 12, and 13 of Fig. 9, theparts above each of said dotted lines being removed. Figs. 14, 15, 16,and 17 are respectively plan views taken on line 1O of Fig. 9, showingthe positions of the calns when the lever isset, respectively, at thepositions shown in Figs.

For purposesV of description one .throughtrack is lettered A B, whilethe opposite through-'track is lettered C D. Each single letterrepresents the portion of the track between tlIe point where the letteris located andthe center line e f of the crossing. At some points in thespecification these portions designated by letters will be referred toas ends of the crossing.

Referring to the drawings, 21 and 22 are respectively the curvedstock-rails of mechanism of the class described, being connected l and CD, which cross each other, by means of the mechanism of our invention.Inside of these curved stock-rails are bent connecting-rails 23 and 24.Pivoted to the ends of these bent connecting-rails are the switchpoints25, 26, 27, and 28. Inside of the bent connecting-rails just describedare straight connecting-rails 31, 32, 33, and 34, connecting at theirouter ends (beyond the figure) to an ordinary frog, which is in turnconnected to the inner rails of the main tracks, which cross each other,by means of our mechanism. n the inner ends of these straightconnectingrails 31, 32, 33, and 34 are movable switchpoints 35, 36, 37,and 38, pivoted, respectively, at 39, 40, 41, and 42. These movablepoints are tapered at their ends in the angular lines 43, 44, 45, and46, conforming to the angle of the bent connecting-rails, so that thesemovable points may be moved against the bent connecting-rails, and theconnecting-rail, movable point, and the straight stock-rail to which themovable point is pivoted form a continuons rail. Inside of the mechanismjust described are the curved connecting-rails 47 and 48. Pivoted to theends of these curved connecting-rails at 49, 50, 51, and 52 areswitch-points 53, 54, 55, and 56. The outer edges of these switch-pointsare cnt away in the angular lines 57, 58, 59, and 60 in such a way thatwhen one of these switchpoints is brought in contact with the straightconnecting-rail the curved rail, the switchpoint pivoted to it, and thestraight connecting-rail form a continuous track. The outer edges of theswitch-points 25, 26', 27, and 28 are cut away in the angular lines 61,62, 63, and 64, so shaped that when these switchpoints are moved ontheir pivots 65, 66, 67, and 68 so that one of the points is brought incontact with the curved connecting-rail to which it is adjacent the bentconnecting-rail to which the switch-point is pivoted, the switch-point,and this curved connecting-rail will form a continuous track. Theswitchpoints 25 and 54 are connected together by tie-bars 71, whichpermit of their being moved together. In a similar manner switch-points53 and 26 are connected by tie-bar 72, switchpoints 27'and 56 by tie-bar73, and switchpoints 55 and 28 by tie-bar 74. Bolted to theswitch-points 25, 53, 54, 26, 27, 55, 56, and 5s are lugs 75, 76, 77,7s, 79, so, s1, and s2. Passing below these lugs on the ends of each setof switch-points are head-rods 83 and 84, the same being connected tothe lugs just described by bolts 85 in the manner illustrated in Fig. 6,so that when these head-rods are moved back and forth longitudinallyacross the rails the four switch points connected to each head-rod willbe moved simultaneously in the same direction. vSecured to the movablepoints 35, 36, 37, and 38 are other lugs 86, 87, 88, and 89similar tothose just described, and illustrated in Fig. 6. Passing under the railsnear the center of the crossing are movablepoint head-rods 91 and 92,rod 91 being conyable mechanism.

.Iournaled in suitable stationary standards 95, 96, 97, and 98, theformertwo adjacent to head-rod 83 and the latter two adjacent tohead-rod 84, as shown, are upright signal posts or masts 99, 100, 101,and 102. Secured to these posts are signal-targets having red signals103, 104, 105, and 106 and white signals 107, 108, 109, and 110. Thesesignalmasts 99 to 102 are connected to the respective head-rods to whichthey are adjacent by slotted lever-arms 111, 112, 113, and 114. Thesignal post or mast 99 is so arranged that it shows white along the maintrack A when switch-point 25 is adjacent to the curved rail 21 and redwhen it is not. The signal on post 100 is so arranged that it showswhite along the main track C when switch-point 26 is adjacent to curvedrail 22 and red when it is not. The signal on post 101 is so arrangedthat the signal shows white on track D when switch-point 27 is adjacentto curved rail 21 and red when it is not. Post 102 is so arranged thatthe signal on it shows white ou track B when switch-point 28 is adjacentto the curved rail 22 and red when it is not. Pivoted at 117 to a tie orother fixed point is a bell-crank 118, having one arm pivotallyconnected to the end of head-rod 83 and having its other end pivotallyconnected at 120 to the connecting-rod 1217. Similarly pivoted at afixed point 123 is another bell-crank 124, having one arm pivotallyconnected at 125 to the head-rod 84 and havingits other end pivotallyconnected at 126 to the connecting-rod 1273. Pivoted at a fixed point128 is a bellcrank 129,having one end pivotally connected at 130 tomovable-point head-rod 91 and the other end pivotally connected at 131to a short link 132, connected at 133 to the connectingrod 121.Similarly pivoted at 135 is another bell-crank 136, having one armpivotally connected at 137 to movable-point head-rod 84 and its otherarm connected at 138 to a short link 139, connected at 140 to theconnectingrod 127.

Mounted adjacent to the above-described mechanism on a suitable base 143isa fourway switch-stand frame 144. v Journaled in the switch-stand is ashaft 146, having rigidly secured to it by a pin 147 or other suitablemeans a lever-arm 148. This lever-arm has an extension-handle 149,pivoted at 150 in such away that when it is desired to turn the shaft146 the arm may be raised toa horizontal position to obtain anadditional leverage,

and when the mechanism is at rest the handle may be lowered to thevertical position shown in Fig. 8 and rest in one of the four notches151,152, 153, and 154, cut in the top 155 of the switch-stand, therebylocking the lever 148 in a fixed position until such time astheextension-lever 149 is raised out ofthe notch. Rigidly secured to the`lower end of shaft 146 are two cams 157 and 158, placed at right anglesto eachother and shaped substantially as shown. Connecting-rod 121 has aslot 159, adapted to allow the rod to tit over `shaft 146, and hasbearing-faces 161 and 162,

adapted` to tit against the sides of cam 157. In a similar manner therod 127 has a slot 163,1n it, adapted to tit over the shaft 146, and hasbearing-faces 164 and 165, adapted to bear againstthe cam 158, the rodhaving the portion 159 passing under said cam, as shown in Fig. 9. Thesecams are so shaped and arranged that starting when they are in theposition shown in Fig. 14 and the lever 148 is accordingly in positionshown in Fig. 1 and moving the lever a quarter of a revolution to theposition shown in Fig. 2' the connecting-rod 127 will be drawn inwarduntil the parts are in the position shown in Fig. 15, the connecting-rod121 remaining stationary during the operation. When the lever 148 ismoved another quarter of a revolution to the position shown in Fig. 3,the connecting-rod 121 will be moved outward to the position shown inFig. 16, the rod 127 remaining stationary. When the lever 148 is movedanother quarter of a revolution to the position shown in Fig. 4,connecting-rod 127 will be moved outward to the position shownV in Fig.17, the rod 121 remaining stationary, and when the lever 148 is moved onaround the circle to its original position the connect'- i ing-rod 121will be again moved inward to the position shown in Fig. 14, rod 127remaining stationary. In other words, the cams are so shaped that duringeach quarter of the motion of the-lever in one quadrant of its swing oneof the connecting-rods is movingin one direction, the same rod beingmoved inthe opposite direction when the lever isin the opposite quadrantof its circle of motion, and when one rod is moving in either directionthe opposite connecting-rod remains stationary.

` In the operation of our invention we rst set all of the parts in thepositionshown in Fig. 1, in which the lever-handle is in the positionshown, the cams being in the position of Fig. 14. In this position therails are set for main track A B and the masts 99 and 102 are turned sothatthe white signals 107 and 110 appear on said track, while the masts100 `and 101 are so set that the red signals 104 and 105 appear upon theopposite track C D. In this position the two white signals 107 and 110,considered together, indicate to the engineer approaching from eitherdirection on `thetrack A B, which these signals control,

through the crossing on the main track. The signal nearest to him alsoconveys to him the information that the switch nearest to him is not setfor slip-switching. On the other hand, the presence of the red signals104 and 105 indicate to the engineer approaching on the opposite track CD from either direction that the track is not set for through traffic,and the signal nearest to him indicates to him that the switch at thatpoint is set for slipswitching; but it does not give him permission toproceed onto the slip-switch. We now raise the handle 149 and turn thelever, 148 a quarter of a revolution to the position shown in Fig. 2 andlet the handle drop down into its notch in the stand, thereby lockingthe parts in position. In making this quarter of a revolution we movethe cams of the stand to the position shown in Fig. 15, thereby drawingin the connecting-rod 127, which has moved the movable-point head-rod92, and consequently moved the movable point 37 on track B away from thebent connecting-rail 23 and the movable point 38 on track D into contactwith the bent connectingrail 24. This motion of the lever-handle 148 hasalso simultaneously moved the head-rod 84 to the left, thereby movingswitch-point 27 against curved stock-rail 21, switch-point 55 against'straight connecting-rail 33, switch-point 56 away from straightconnecting-rail 34, and switch-point 28 away from curved stock-rail 22.During this motion the points in tracks A and C remain stationary. Inthis position the mechanism is set, as shown, for slipswitching fromtrack B to track O, or vice versa. This motion of the lever has alsoturned the signals on masts 101 and 102 a quarter of a revolution, sothat the red signal 106 now shows on the track B and the white signal109 shows on track D. The signals ICO now show an engineer approachingthe crossy ing from either direction on either main track one red andonewhite signal set against him `on his own main track. An engineerapproaching on tracks B or C will find the red signal on hisown tracknearest to him as he approaches and the corresponding red signal on theslip-switch to which he desiresto go, these two red signals indicatingto him that he can pass around from track B to C, but cannot pass from Cto D or A to B--in'other words, that the main-line crossing is closed.We now raise the handle 149 and move the lever 148 another quarter of arevolution to the position shown in Fig. 3 and again let the lever 149drop, locking the parts in position. This motion has moved the rod 121upward to the position shown in Figs. 2 and 16, which IIO IThe tracksare'so set that both signals on these tracks show white, while thesignals on tracks A and B show red. In the above movement the parts ymoving rod 127 outward and the movable points and switch-points ontracks B and D to the position shown in Fig. 4, the movable points beingmoved to the left, the four switch-points being moved to the right, thesignals on track B being moved to white and on track D to red. Duringthis motion the parts on tracks A and C are stationary. In this positionit will be seen that slip-switching is afforded from track D to track A,or vice versa, and that the two signals on said track D indicate red,while the two signals on tracks C and B indicate white. `We now move thelever another quarter of a revolution and return the parts to theirfirst position. The lever may now be moved around again in the same orreverse direction, as desired, in the latter case reversing the order ofsuccessive positions of the parts.

We desire to call particular attention to the fact that we are the rstto move the switchpoints andthe movable points in one end of thecrossing simultaneously by one lever mo# tion, while the switch-pointsand the movable pointsin the otherend of the crossing remain absolutelyat rest, and that by this feature We obtain the two results of, first,being able to have each of the four separate positions of thecontrolling-lever set the mechanism for a ldirect crossing on one track,a slip-switch from one track to the other, a track-crossing ways beingopen at a time.

on the opposite through-crossing and for the opposite slip-switch, onlyone of said passage- We are also by this construction able to so operatethe signals that, as described, the signal nearest the engineer as heapproaches the crossing always indicates to him Whether or not theswitch nearest to him is set for the main line or for slip-switching andalso that the two signals on opposite portions of the same main trackindicate, when taken together, whether or not the main track is clearfor a crossing.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-
